klambeth, I've never heard of it, but I would be careful not to eat too little. It CAN hurt! Generally, unless being supervised by a physician, it isn't recommended women eat fewer than 1200 calories -- and that would be for women who only have a few pounds to lose.
The more we weigh, the more calories we need to do everything in our life. So, at 1200 calories, it would be very difficult for you to get in all the calories and nutrients you need to function well. You may be able to do it for a while, but it is NOT a lot of calories and many people find it isn't sustainable. And if you stall, there is nowhere lower to go!
While everyone is different, you might find that starting on 1600-1800 calories a day is low enough to lose 1-2 pounds a week and be sustainable. If it's too many calories, you can always drop 100 or so a day and see what happens...
